To fill out a bank money order, write the recipient’s full legal name on the “Pay to the Order of” line, print your own name and address in the purchaser field, add the account or invoice number on the memo line, and sign the front. The whole thing takes about two minutes. The order of operations matters more than the speed: fill in the payee first, before you leave the counter, because a blank payee line turns the money order into something close to cash that anyone could claim.
What to Have Ready Before You Write
Two pieces of information decide whether the money order works: the exact legal name of the person or business you’re paying, and the dollar amount. Getting the name right matters more than anything else on the form. A misspelled or incomplete name gives the recipient’s bank a reason to refuse payment, and once ink hits the paper most issuers won’t let you white it out or write over it. You void the money order and buy a new one.
If the payment is for a bill, bring the account number or invoice number too. That goes on the memo line so the payment gets credited to the right account on the other end.
The Four Fields to Complete
Money order forms look slightly different from issuer to issuer, but the fields are essentially the same everywhere.
Pay to the Order of. Write the full legal name of the person or company receiving the funds. This is the most important line on the form. Only the person or entity named here can cash or deposit the money order. Fill this in immediately after purchase.
Purchaser or “From” field. Enter your full legal name and current mailing address. This tells the recipient who sent the payment and gives them a way to reach you if something goes wrong.
Memo or account number line. Write the account number, invoice number, or a brief note explaining what the payment covers. This line is technically optional, but skipping it means trusting the recipient’s office to figure out where to apply your money.
Signature line on the front. Sign the front of the money order. Do not sign the back. The back is reserved for the recipient’s endorsement when they go to cash it.
Pen Choice and Mistakes
Use a black ink pen, and a gel pen if you have one. Gel ink resists a fraud technique called check washing, where criminals use chemicals to dissolve standard ballpoint ink and rewrite the payee name or amount.
If you make a mistake, don’t try to correct it on the form. Cross-outs, whited-out fields, and overwritten names all give the recipient’s bank a reason to reject the money order. Ask the teller to void it and issue a replacement while you’re still at the counter.
The face value itself isn’t something you write. After you pay, the teller or machine prints the exact dollar amount onto the money order. That printed amount is a security feature. Because it’s machine-generated, no one can alter the face value after the money order leaves the counter.
Keep the Receipt With the Serial Number
When you complete the purchase you’ll get a receipt or detachable stub showing the money order’s serial number. Do not throw this away. That serial number is the only way to track the payment or get a refund if something goes wrong. Without it, tracing a money order is difficult and sometimes impossible.
Some banks let you check the status of a money order through their online portal or automated phone system. USPS offers inquiry services by mail using Form 6401, which requires the serial number from your receipt.1United States Postal Service.

A Few Limits Worth Knowing
Most money orders cap at $1,000 per instrument, so a larger payment means buying more than one and filling out each the same way. USPS money orders never expire and don’t accrue interest, so a lost one you find later is still good.2United States Postal Service. Sending Money Orders Bank-issued and retail money orders follow different rules; some issuers begin deducting monthly service charges from the face value after one to three years of inactivity, which can eventually reduce the money order to zero. Cashing promptly avoids the problem entirely.
